System: Arch Linux (64 bit), GNOME 3.22.3Situation: Two nested splittergadgets created with the form designerProblem: form designer doesn't show hierarchy correctly and after switching to source code and back it is completely messed up. Also the anchoring is messed up and scaling up the window leads to a even higher scale of the splittergadget.

FormMain.pbf:

Code:

;; This code is automatically generated by the FormDesigner.; Manual modification is possible to adjust existing commands, but anything else will be dropped when the code is compiled.; Event procedures needs to be put in another source file.;
